摘要：

Aromatic polyamides and polyimide having oligodimethylsiloxane of defined length (1-4 Si atoms) in main-chain or in side-chain were synthesized by polycondensation of bis(4-aminophenyl)-functionalized oligodimethylsiloxanes with acid dichloride or pyromellitic dianhydride. Glass transition temperature and gas permeability of the polymers were markedly influenced by the introduction of oligodimethylsiloxane components into the polymer. The effects was more notable in polymers having oligodimethylsiloxane as side-chains.
